FVX15 comes with a grille (not
shown in photo). It uses our new Hypex module based HX405 amplifier.
We also develop a new DS1502 driver is two stacked 25mm magnets
to improve excursion limit. Its physical dimension is exactly same
as FV15HP. As a result, one can expect
the full benefit of FV15HP design albeit with 2.5db less output.
The quickguide of the amplifier can be found
here .

FVX15, a lower power version
of the our well regarded FV15HP, is our answer to the need for a
"bang for buck" home theatre solution that retains the
dynamic and accurate bass that we have become known for. Correctly
integrated, our vented subwoofers can achieve the tight bass normally
associated with a sealed enclosure, yet with greater low frequency
output. We recommend this subwoofer for systems in which home theatre
has a high priority. FVX15 also features multi-tune capability.
Customers can select either one-port or two-port operation.

Direct Servo Technology

All our subwoofers use our patented Direct Servo technology. The servo enables precise control over the cone which is essential for tight, dynamic and accurate bass. It also counteracts many different driver non-linearities and allows us to use lighter drivers which avoid the need for excessive amounts of amplifier power.
